Charter Spectrum's Apple TV App and Zero Sign-on May Not Arrive Until 2019
At the same time, Apple said the feature would first work with Charter Spectrum, with support expected to be implemented "later this year," aka some point before December 31, 2018. Charter Spectrum is expected to debut a new Apple TV app that will enable the feature and allow Charter Spectrum subscribers to watch cable content on the Apple TV.
It looks like the rollout of the Charter Spectrum app and the Zero sign-on feature is not going to make that deadline, as Apple today updated its Apple TV 4K page to change some of the wording to reflect the delay.
Rather than stating that Charter Spectrum cable subscribers will be able to watch live channels and on-demand programs with Apple TV "later this year," the page now says that the feature is "coming soon."
Prior to today's wording change: "And later this year, Charter Spectrum cable customers can watch live channels and thousands of on-demand programs with Apple TV."
After the wording change: "And coming soon, Charter Spectrum cable customers can watch live channels and thousands of on-demand programs with Apple TV."
That Apple has swapped "coming soon" for "later this year" suggests the Charter Spectrum app and the Zero Sign-on feature will be coming sometime after 2018, perhaps early in 2019.
